The high-voltage test transformers under UHV Power can help many power workers conduct various power tests more conveniently.
This test transformer is widely used in the power industry and is highly welcomed by power workers. At present, test transformers are divided into several types: dry-type test transformers, oil immersed test transformers, and gas filled test transformers. Different types of test transformers are different.
The dry-type test transformer is made of coil epoxy resin vacuum casting and is an important equipment for insulation strength and withstand voltage testing. This test transformer is suitable for on-site testing of insulation performance of various electrical equipment in power systems and power users. The coil winding and CD type iron core adopt a new technology of epoxy resin vacuum casting.
Compared with oil immersed test transformers of the same capacity and voltage, dry-type test transformers reduce leakage magnetism, improve insulation strength and moisture resistance. And it has the advantages of light weight, small size, relatively stable performance, easy to use and carry, and no oil leakage.
Oil immersed test transformers are suitable for insulation strength testing of various electrical products, electrical equipment, insulation materials, etc. under specified voltage to evaluate the insulation level of the product, discover insulation defects of the tested product, and measure its insulation capacity. Endure overvoltage.
Suitable for insulation strength testing of various electrical products, electrical equipment, insulation materials, etc. under specified voltage, evaluating the insulation level of the product, discovering insulation defects of the tested product, and measuring the ability to withstand overvoltage. It is a basic testing equipment for power stations, power supply and distribution systems, and scientific research institutions.
Inflatable test transformers, this series of products basically includes three basic parameters: 5-50, 10-100, and 10-150. They can also be customized according to customer needs. Compared with traditional oil immersed lightweight test transformers, the weight is reduced by 20% -60% (depending on voltage and capacity level), and there is no oil pollution. The voltage level of a single test transformer can reach 400kV.
The inflatable test transformer adopts new materials and technologies, using sulfur hexafluoride gas as the medium. Due to its excellent insulation performance and the arc extinguishing characteristics of sulfur hexafluoride gas, the YDQ inflatable transformer test transformer is non combustible, greatly improving the service life and test accuracy of the transformer. Compared with traditional oil immersed transformers and dry-type test transformers, YDQ gas filled test transformers have better performance, and the volume and weight of gas filled transformers are greatly reduced. Due to the adoption of new production processes, the technical performance of the product has been greatly improved, making it particularly suitable for on-site operations and frequent moving conditions.
